I put my list of references into Microsoft Word in two columns.
Here is what I include
Their full name and the first name they go by
Their home address
Their City, state, ZIP code
Their telephone number
Their e-mail address
Relationship to me (ie, former supervisor at what location), and how long I've known them.
I list 3 personal and 3 professional references. For the professional references I use co-workers, not supervisors.
